Dear Sir

My self Arvind Kumar I am using Airtel DTH customer Id 001. I have spoken with Customer care officer dated 20 july 2018 to change my airtel dth plan by Rs219. he told me you can recharge with 219 and yours plan willl be shifted automatically on rs219 but till date it was not shift. My plan is running on Rs 315.

I call again customer care he replied yours plan could not shift to rs 219.
